Options Trading: What Are Options and How Do They Work?

BY TIO Staff

|May 29, 2024

Options trading represents a facet of the financial market that allows traders to speculate on the price movement of an asset without the need to own the underlying security. This form of trading offers flexibility and the potential for high returns, but it also comes with its own set of risks and complexities.

Understanding Options

At its core, an option is a contract that gives the buyer the right, but not the obligation, to buy or sell an underlying asset at a predetermined price on or before a specific date. Options are divided into two main categories: calls and puts.

Call Options

A call option gives the holder the right to buy an asset at a set price within a specific timeframe. Traders buy call options when they anticipate that the price of the underlying asset will rise. This allows them to lock in a purchase price that could be lower than the market value in the future, potentially leading to profits.

However, if the market price does not exceed the strike price (the predetermined price) before the option expires, the call option will expire worthless, and the trader will lose the premium paid for the option.

Put Options

Conversely, a put option gives the holder the right to sell an asset at a set price within a specific timeframe. Traders buy put options when they believe the price of the underlying asset will fall. This enables them to sell the asset at a higher price than the market value, potentially leading to profits.

Similar to call options, if the market price does not fall below the strike price before the option expires, the put option will expire worthless, resulting in a loss of the premium paid.

How Options Trading Works

Options trading involves buying and selling options contracts on various financial instruments, including stocks, commodities, and indices. The process is facilitated through options markets, where traders can engage in transactions with other market participants.

Opening a Trade

To open a trade, a trader must first decide whether they want to buy a call or put option based on their market outlook. They then need to select the strike price and expiration date for the contract. The cost of an option is known as the premium, which is determined by several factors including the underlying asset's price, volatility, time until expiration, and the strike price.

Closing a Trade

Traders can close their options positions in three ways: exercising the option, selling the option, or letting the option expire. Exercising means the trader decides to buy or sell the underlying asset at the strike price. Selling the option involves selling the contract to another trader before it expires. If an option is out of the money (not profitable) at expiration, it will expire worthless, and the trader will lose the premium paid.

Risks and Benefits of Options Trading

Options trading offers the potential for high returns, but it also carries significant risks. Understanding these risks and benefits is crucial for anyone considering options trading.

Benefits of Options Trading

  • Leverage: Options allow traders to control a large amount of the underlying asset with a relatively small investment (the premium).
  • Flexibility: Traders can use options for various strategies, from simple bets on market direction to complex combinations that limit risk.
  • Hedging: Options can be used to protect other investments from adverse price movements.

Risks of Options Trading

  • Complexity: Options strategies can be complex and difficult to understand for beginners.
  • Time Decay: Options have an expiration date, and their value decreases over time, which can lead to losses if the market does not move as anticipated.
  • Potential for Losses: While the premium paid for an option is the maximum loss for a buyer, sellers of options can face much larger potential losses.

Strategies for Options Trading

Options trading offers a wide range of strategies that traders can employ to achieve their financial goals. These strategies can vary in complexity and risk levels, catering to different trading styles and objectives.

Basic Options Strategies

For beginners, basic options strategies provide a foundation for understanding how options work and how they can be used to generate profits. Some common basic strategies include buying call options for bullish bets and buying put options for bearish bets.

Advanced Options Strategies

Advanced options strategies involve more complex combinations of options contracts to achieve specific risk/reward profiles. These strategies often require a deeper understanding of options pricing and market dynamics. Examples of advanced strategies include straddles, strangles, and iron condors.

Factors Influencing Options Prices

Several factors impact the price of options contracts, influencing their value and potential profitability. Understanding these factors is essential for successful options trading.

Underlying Asset Price

The price of the underlying asset plays a significant role in determining the value of an option. For call options, as the underlying asset's price rises, the option becomes more valuable. Conversely, for put options, as the underlying asset's price falls, the option's value increases.


Volatility measures the degree of price fluctuations in the underlying asset. Higher volatility generally leads to higher option prices due to the increased likelihood of significant price movements. Traders often seek out volatile assets for options trading to capitalize on price swings.

Time to Expiration

The time remaining until an option's expiration date also affects its price. Options with longer expiration periods tend to have higher premiums since there is more time for the underlying asset's price to move in a favorable direction. As the expiration date approaches, the option's value may decline rapidly due to time decay.


Options trading offers a unique set of opportunities and challenges. It requires a good understanding of the market, a clear strategy, and careful risk management. While the potential for high returns exists, traders must also be aware of the risks and complexities involved. As with any investment, education and caution are key to navigating the options market successfully.
